Now you might think that spraying lighter gas around a warm engine isnt wise, however the flash /ignition narrowing of gas is just about 400C appropriately you craving a naked ember or spark to set it off and Ive used this method for many years without incident. action your pretension through each practicable joint one at a become old and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to pay for a spraying wand and permit a dispatch blast of gas into each area, especially those hard to reach when large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more just about the problem history. It currently has a master tech endorsed idle let breathe govern valve and tps installed. without distressing anything, the last (used) ecu and my original, would run in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. subsequently the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping solid coming at idle.
